Test for the primary vision disorder in children, refractive error, with this child-friendly unit that engages youngsters, puts them at ease, and requires minimal cooperation.
Features and Benefits
• Five-second, automatic test makes patient compliance easier.
• Minimal cooperation needed, making it effective for children, disabled patients and those with language barriers.
• Measures and indicates abnormal readings automatically—no provider interpretation required.
• Operates at a nonthreatening 14 inches (35 cm) distance.
• Screens for common vision problems, including near- and farsightedness (myopia/hyperopia), astigmatism (asymmetrical focus) and anisometropia (unequal power between eyes).
• Automatically screens for common vision problems, including near and farsightedness (myopia/hyperopia), astigmatism (asymmetrical focus), and anisometropia (unequal power between eyes).
• Features optics and electronics shock-mounted inside housing to protect unit.
• Test patients while they’re wearing glasses or contact lenses—testing for symptoms caused by the need for a new optical prescription
• Reliability Number: indicates the number of good readings obtained and their consistency, based on a 1 to 9 scale (higher numbers are better).
◦ > 6 is typically acceptable.
◦ 5 is marginal / repeat the test if possible.
◦ < 4="" is="" poor="" repetition="" of="" the="" test="" is="" />
• S / Sphere: Power of the eye measured in diopters. Negative numbers indicate myopia (near sightedness), positive numbers indicate hyperopia (far-sightedness).
• C / Cylinder: Measure of astigmatism, or irregular focus of the eye.
• D / Difference: Difference in the mean spherical power between the two eyes (displayed in child mode only).
